KINDERMAN M. BOBLETT, OF TOLEDO, OHIO.

RADIATOR.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed April 1, 1912. Serial No. 687,619.

To all whom it may concern:

Be it known that I, KINDERMAN M. BOB- LErr, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

My invent1on relates to fluid cooling apparatus, or condensers, and particularly to radiators for use in connection with explosi've engines, and is especially adapted for automobile use. i

roved form of radiator which will present to the atmosphere a maximum amount of radiating surface, which will be stanch and compact, and which will comprise a plurality of identical units'which are assembled to form radiators of different sizes or proportions.

With the above primary and other incidental objects in view as will more fully appear in the specification the invention consists of the features of construction, the parts and mode of operation or their equivalents, as hereinafter described and set forth in the claims. I

Referring to the drawings, Figure 1 is a front elevation of the assembled radiator. Fig. 2 is a detail perspective view of one of the. radiator units somewhat expanded to better show the configuration of the strip of material from which the unit is constructed. Fig. 3 is a detail transverse sectional view. Fig. 4 is a detail perspective view of several radiator units adjusted side by side illustrating the intermediate water passages or conduits between succeedin units. Fig. 5 is a detail sectional view disclosing the water passages orv conduits. Figs. 6, 7, 8

the invention is to simplify combinations thereof, and the and 9 are perspective views of modifications of the constructions shown in Figs. 2 to 5.

Like parts are indicated by similar characters of reference throughout the several vlews.

The radiator forming the subject matter hereof is of the-cellular type presenting a front surface of pleasing appearance divided into a multitude of angular cells of equal proportion.

In constructin the radiator there is employed a main rame having in its upper portion thereof a receiving chamber 1 and in its lower portion a dispensing chamber 2 connected with the receiver chamber by a plurality of conduits through which the water passes from the chamber 1 to the chamber 2. These conduits may be either continous from one chamber to the other in the manner well known in radiator construction or they may be of short length and arranged in tiers separated by intermediate water spaces or auxiliary chambers common to all the conduits of the tier as shown in Fig. 1.

The conduits are formed b arranging a plurality of similar units si e by side but separated one from the other to form intermediate water spaces or passages. The units which are all identical in construction are each formed of a single continuous strip or material folded or-bent upon itself at intervals into a series of loops or bights to form a succession of cellular spaces. In the construction shown in Figs. 2 to 7 inclusive there are formed two parallel series of rectangular cells, while the constructions shown in Figs. 8 and 9 disclose single series of triangular cells.

In constructing the unit the strip of material is bent upon itself at intervals throughout a succession of bends or bights to form a series of loop like convolutions thereby. producing a meandrous design. The meander line upon which the strip is bent varies slightly to produce the difierent designs shown in Figs. 6 to 9 inclusive.

In the construction shown in Figs. 2 to 6 which embodies two series of cellular with those ofthe other series, a stri of material is carried laterally, as at 7, rom one side to the other of the unit, then is bent at right angles to form one side of the unity.

as at 8, and is extended a distance of one space or cell. It is then bent inward orlaterally, as at 9, a distance of one space or, cell thence longitudinally, as at- 10, to form so extended a distanceequal to one space or cell and is thence carried laterally, as at 7, to the opposite side of the unit. The same sequence of angular bends is repeated throughout the .unit. The particular convolution of the strip formed by its succession of angular bends or meandrine turns is clearly illustrated in Fig.2 in which the unit is shown in a recumbent position.

Fig. 7 discloses a'construction similar to Fig. 6 except that the cellular spaces of one series do not register with those of'the other series but are offset in relation thereto. The unit illustrated in Fig. 7 is formed by extending the strip of material laterally, as at 12, a distance equal to one space or cell, or to half the width of the unit, thence longitudinally, as at 13, to form an intermediate septum a distance of one half a cell or space thence laterally, as at 14, a full cell or space to the opposite side of the unit, whereupon the strip is bent longitudinally, at right angles as at 15 to form the side of the unit and is so extended the distance of one space or sell thence is bent inward an equal distance, as at 16, and longitudinally, as at 17 a half space or cell thence laterally, as at 18, a distance equal to one space or cell to the side of the unit from which the strip originally started and is thence extended lon gitudinally at right angles, asat 19, forming one side of the unit a distance of one cell, whereupon this sequence of angular bends is repeated throughout the length of the unit.

In the construction shown in Fig. 8 there is disclosed but one series of cellular spaces which are triangular in form and in this case are more particularly in the form of a right angled triangle. The unit is formed by extending the strip of material-laterally from one side to the other of the unit, as at 20, thence longitudinally, as at 21, to form one side wall thereof a distance of one space from which point the strip is extended diagonally upward and laterally, as at 22 to the starting point at the opposite side of the unitfrom which point it is extended longitudinally, as at 23, to form the opposite walls of the unit a distance of one space and is projected then laterally, as at 20, to the opposite side of the unit thereby completing one sequence of bends or convolutions which sequence is repeated a number of times to-complete the unit. In order that each cell may rest firmly upon the next cell of the series a flattened surface 4; is provided adjacent to each angle of the cells.

Fig. 9 discloses a construction embodying a single series of trianguluar cells which differ from the triangular cells of Fig. 8 only in that they are isosceles in form instead of right angled. In constructing the,

unit shown in Fig. 9 the strip of material is extended diagonally across the unit from one side to the other thereof, as at 24, thence longitudinally, as at 25 to form one side wall of the unit from which point it is extended diagonally upward, as at 26, to the starting fiat surfaces of the succeeding unit when the units are arranged side by side as shown in Fig. 4. These lateral shoulders 5 serve to space the units one from the other thereby providing intermediate water spaces or passages 3 of which said shoulders 5 form the end walls. In addition to bein provided with the lateral shoulders or le ges 5 the side walls of the units are preferably though not necessarily provided with grooved depressions 6 which as shown in Figs. 2 to 5 inclusive are located in the outward lateral wall of each of the cellular spaces and intermediate the lateral projecting shoulders or ledges 5. These grooved depressions or beads formed in the side walls of the radiator unit serve to strengthen and stiffen the unit and furthermore provide a series of enlargements within the water spaces or conduits as is clearly shown in Fig. 5 thereby giving to the water a more or less tortuous passage from one chamber to the other. The radiator units as herein described may .be formed in continuous sections of great length to be divided subsequently into shorter lengths according to the dimensions of the radiator to be constructed. Inasmuch as the radiator unit is formed throughout of but a single strip of material the possibility of leakage is reduced to minimum. As each radiator unit comprises but a single strip and all of the radiator units employed are identical the cost of construction is reduced to minimum. 'After the several radiator units have. been arranged side by side as shown in Fig. 4 they are dipped into molten solder or are otherwise united one to the other by any suitable method whereby the plurality of radiator units will be formed into an integral body, or core. It is to be noted that the construction described provides a broad fiat surface at opposite terminals of the unit to facilitate the connection of the core or body with the chambers.

From the above description it will be apparent that there is thus produced a device of the character described possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

lVhile in order to comply with the statute, the invention has been herein described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to' any spesitely disposed loops,

cific details but that the means and mechanism herein shown and described comprise but one mode of putting the invention into effect and the invention is therefor claimed broadly in any of its possible forms or modifications Within the scope of the appended claims.
